Abstract: PURPOSE: To obtain a back light for liquid crystal display device and a liquid crystal display device where a light source can be safely and easily replaced in perpendicular from the rear side in a small space and the cost is reduced. CONSTITUTION: A lamp guard unit 26 of a back light 20 is freely detachable from a lamp hold unit 24, which is fixed to a light transmission plate 22, in the direction orthogonal to the light irradiated face of the light transmission plate 22. Consequently, it is unnecessary to replace the whole of the back light 20 when a fluorescent lamp 44 is replaced, and a user is safe because he doesn't touch the fluorescent lamp 44 difficult to handle, and further, only a small space is required for detachment ecause it is pulled out in the perpendicular direction, and thus, the fluorescent lamp 44 is safely and easily replaced in the small space.

Abstract: PURPOSE: To display an image with a fixed quality on a liquid crystal display device regardless of the change of length of the period for applying a voltage of the same polarity to the liquid crystal. CONSTITUTION: The length of one period of a horizontal synchronous signal inputted from an information processing device to a LCD unit is counted, and on the basis of the length of one period and whether a gate overlap scan is performed or not, the amplitude and center of amplitude of the data voltage applied to a liquid crystal are corrected in such a manner that the amplitude of the data voltage is increased, and the correction quantity to the center of amplitude is increased as the length of the period of applying the data voltage of the same polarity to the liquid crystal is shortened. Thus, in both cases of a relatively long period and a short period, the absolute values V of the voltage between electrodes before and after TFT is OFF are equal to each other regardless of the polarity of the data voltage applied to the liquid crystal.

Abstract: PURPOSE: To prevent the generation of flicker, etc., when the contrast of an image to be displayed is changed. CONSTITUTION: The amplitude of a data voltage, of which the polarity is inverted at timing synchronized with the display cycle of the image, is changed corresponding to gradation and instructed contrast and the position of 0V (center) corresponding to the amplitude of the data voltage is offset by much offset quantity according to the increase of contrast. Thus, even when the instructed contrast is comparatively high and the amplitude of the data voltage is comparatively small as shown in (A) or even when the instructed contrast is comparatively low and the amplitude of the data voltage is comparatively large as shown in (B), a change ΔV of an inter-electrode voltage caused by the influence of parasitic capacitance of a TFT in the case of turning off the TFT is corrected and after the TFT is turned off, the inter-electrode voltage is made equal in spite of the polarity of data voltage to be impressed to liquid crystal.

Abstract: PURPOSE: To prevent the flowing of melted solder to neighboring input electrodes, to perform the processing for avoiding the concentration of stress in the shearing direction applied on the input electrodes, and to prevent the short circuits and the wire breaking between the electrodes. CONSTITUTION: The long side of a slit hole 26 in correspondence with each input electrode 28 has the irregular shape. The input electrode 28 is overlapped on a substrate electrode 30. A solder 32 is melted by heating, and both electrodes 28 and 30 are fixed. The melted solder 32 flows between a base 22 and a substrate 18A by capillary phenomenon. The flow of the solder to the neighboring input electrode 28 is blocked by forming a protruding part 26A on the long side of the slit hole 26 so as to form the irregularity and setting the base 22 connecting the neighboring input electrodes 28 in the nonlinear state. Furthermore, when a liquid cell and the substrates 18A and 18B are relatively moved, the respective independent deformations can be formed at the bonding part of the protruding part 26A and the individual input electrode 28. The concentration of the stress in the shearing direction is avoided, and the strength is increased.
